Most recent LDL-C greater than or equal to 130 mg/dL (CAD) (DM)
CPT4 code
Name of the Procedure:
Lipid Profile Testing (Evaluation of LDL-C Levels)
Summary
A blood test to measure low-density lipoprotein cholesterol (LDL-C) levels, used to assess cardiovascular health, particularly in patients with coronary artery disease (CAD) or diabetes mellitus (DM).
Purpose
To determine if a patient has elevated LDL-C levels, which is a risk factor for cardiovascular diseases. The goal is to evaluate heart disease risk and guide treatment to lower LDL-C.
Indications
- Patients with a history of coronary artery disease (CAD).
- Diagnosed with diabetes mellitus (DM).
- Family history of heart disease.
Hyperlipidemia or dyslipidemia.
Preparation
- Fasting for 9-12 hours before the blood draw.
- Continuing or adjusting medications only as advised by the physician.
- Complete any prior diagnostic tests as recommended by the healthcare provider.
Procedure Description
- A phlebotomist will sterilize the skin on the patient's arm.
- A needle is inserted to draw blood from a vein.
- The sample is collected in a test tube and sent to a laboratory for analysis.
- The laboratory analyzes the blood to measure the LDL-C levels.
- Results are forwarded to the physician for evaluation.
Duration
Approximately 10-20 minutes for the blood draw. Lab analysis can take several hours to a few days.
Setting
Outpatient clinic, doctor's office, or hospital laboratory.
Personnel
Phlebotomist, laboratory technician, and the ordering physician.
Risks and Complications
- Minor bruising or discomfort at the needle insertion site.
Rarely, infection or hematoma at the puncture site.
Benefits
- Identifies high LDL-C levels which are a modifiable risk factor for heart disease and stroke.
- Helps in guiding dietary, lifestyle, and medical interventions.
Recovery
No significant recovery needed. Patients can resume normal activities immediately.
Alternatives
- Non-invasive lipid profile tests (e.g., fingerstick tests), which may be less accurate.
Genetic testing for predisposition to high cholesterol.
Patient Experience
Patients might feel a brief pinprick during the needle insertion and slight discomfort. Using a cold compress and taking over-the-counter pain relief can manage any minor post-procedure pain.
